2011-07-11iwlagn: separate and enhance the fixed rate fromWey-Yi Guy
For testing purpose, we need better control of msc from user application. Separate the fixed_rate between debugfs and testmode and enforce it. Signed-off-by: Kenny Hsu <kenny.hsu@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-07-11iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic stateMeenakshi Venkataraman
WiFi throughput drops drastically when BT is turned on, BT and WiFi are simultaneously transmitting/receiving traffic. This is particularly true when BT has higher priority over WiFi, and hence the device defers TX frames. The AP assumes that the channel is bad and reduces the data rate, implying longer airtime, which exacerbates the problem further, resulting ultimately in what is popularly called the "death-spiral" phenomenon. The use of PS-poll in such scenarios guarantees a low but consistent throughput. Since the death-spiral phenomenon is observed only when the RSSI is low, use PS-poll only when RSSI is low and disable when high, with a known hysterisis. This feature specifies the high and low thresholds and implements the callbacks registered with mac80211, which will be called when threshold events occur. iwlwifi: dynamic pspoll: optimize rssi monitor code Signed-off-by: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

2011-07-11mac80211: add driver RSSI threshold eventsMeenakshi Venkataraman
mac80211 maintains a running average of the RSSI when a STA is associated to an AP. Report threshold events to any driver that has registered callbacks for getting RSSI measurements. Implement callbacks in mac80211 so that driver can set thresholds. Add callbacks in mac80211 which is invoked when an RSSI threshold event occurs. mac80211: add tracing to rssi_reports api and remove extraneous fn argument mac80211: scale up rssi thresholds from driver by 16 before storing Signed-off-by: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

Now, there are only two functions to send a host command: * send_cmd that receives a iwl_host_cmd * send_cmd_pdu that builds the iwl_host_cmd itself and received flags The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API functions.

2011-07-11iwlagn: add an API to free the TX contextEmmanuel Grumbach
Tx free functions move to the transport layer. Unify the functions that deal with tx queues and cmd queue. Since the CMD queue is not fully allocated, but uses the q->n_bd / q->window trick, the release flow of TX queue and CMD queue was different. iwlagn_txq_free_tfd receives now the index of the TFD to be freed, which allows to unify the release flow for all the queues.

2011-07-08Bluetooth: Add support for returning the encryption key sizeVinicius Costa Gomes

2011-07-08Bluetooth: Add support for storing the key sizeVinicius Costa Gomes
In some cases it will be useful having the key size used for encrypting the link. For example, some profiles may restrict some operations depending on the key length. The key size is stored in the key that is passed to userspace using the pin_length field in the key structure. For now this field is only valid for LE controllers. 3.0+HS controllers define the Read Encryption Key Size command, this field is intended for storing the value returned by that command.

2011-07-08Bluetooth: Fix SM pairing parameters negotiationVinicius Costa Gomes
Before implementing SM key distribution, the pairing features exchange must be better negotiated, taking into account some features of the host and connection requirements.

2011-07-08mwifiex: 4-byte alignment in mwifiex_process_sta_txpd()Yogesh Ashok Powar
In XMIT path, the skb that we get from the kernel itself is not aligned with 4-byte boundary on some embedded platforms. Had it not been the presence of tx_pkt_offset field in txpd, 4 byte memory alignment was not possible without memmove of entire skb. And that would have increased MIPS instead of reducing. With this patch few memory cycles can be saved while fetching interface header and txpd structure because of 4 bytes memory alignment.
